My dad used this to power his tv sound. When he passed it came to me. The unit seems to be in very good condition. I've tested everything I know how to test. All the speaker channels appear to work fine. There are a few screws missing that secure the cabinet to the chassis. You can buy a full screw set for about $10. I put in some matching screws and the unit is very solid, but you may want to put a few more in. This is my first sell on Reverb. I will send anyone my number to discuss. I'm a pro musician but no audiophile. I want to represent this product as realistically as possible. I'm willing to take less than market value, and I truly believe someone will get a good deal.
